Bass Harbor Bridge, Tremont, ME

Northstar Hydro, Inc. provided design services related to hydrologic and hydraulic modeling to VHB, Maine DOT’s contractor, for preliminary design of a replacement bridge at Bass Harbor in Tremont, Maine.  Critical issues at the site include restricted flow that influences tidal water levels inland of the bridge and rapid flow through the bridge.  Upstream of the bridge is Bass Harbor Marsh, much of which is within Acadia National Park.  Hydraulic modeling was designed to provide understanding of flow rate and tidal prism in the Bass Harbor Marsh and to understand the impact of the existing and proposed bridges on tide levels.
